Achieving high fouling resistance and permeability using membrane separation technology in water treatment processes remains a challenge. In this work

a novel mixed-matrix membrane (MMM) (poly(arylene ether ketone) [PAEK

]

-containing carboxyl groups [PAEK-COOH

]

/UiO-66-NH

) with superb fouling resistance and high permeability was prepared by the nonsolvent-induced phase separation method

by

in-situ

growth of UiO-66-NH

on the GO layer

and by preparing hydrophilic PAEK-COOH. On the basis of the structure and performance analysis of the MMM

the maximum water flux reached 591.25 L·m

whereas the retention rate for bovine serum albumin increased from 85.40% to 94.87%. As the loading gradually increased

the hydrophilicity of the MMMs increased

significantly enhancing their fouling resistance. The strongest anti-fouling ability observed was 94.74%

which was 2.02 times greater than that of the pure membrane. At the same time

the MMMs contained internal amide and hydrogen bonds during the preparation process

forming a cross-linked structure

which further enhanced the mechanical strength and chemical stability. In summary

the MMMs with high retention rate

strong permeability

and anti-fouling ability were successfully prepared.
